mirabegron + bisoprolol

This drug is a **combination of mirabegron and bisoprolol**. Mirabegron is a **selective beta-3 adrenergic receptor agonist** primarily used to treat overactive bladder by relaxing detrusor smooth muscle during bladder filling, increasing bladder capacity and decreasing episodes of urge incontinence, urgency, and frequency. Bisoprolol is a **selective beta-1 adrenergic receptor antagonist (beta-blocker)** commonly used for hypertension and cardiac conditions by decreasing heart rate and cardiac output. When combined, bisoprolol can mitigate the cardiovascular side effects of mirabegron (such as increased heart rate and blood pressure); however, it may also blunt mirabegron’s effects on brown adipose tissue thermogenesis, lipolysis, and glucose uptake. This combination is **not a standard approved fixed-dose pharmaceutical product** but has been studied for research purposes, particularly to separate the metabolic effects of mirabegron from its cardiovascular effects[1][2].
